Answer:

m= 5

Step-by-step explanation:

-7m-5(m+5)= -85

-7m-5m-25= -85

-12m-25= -85

-12m= -60

m= 5

Answer:

m=5

Step-by-step explanation:

−7m−5(m+5)=−85

−7m+(−5)(m)+(−5)(5)=−85

−7m+−5m+−25=−85

combine the like terms: (−7m+−5m)+(−25)=−85

−12m+−25=−85

add 25 to both sides : −12m−25+25=−85+25

divide both sides by -12

−12m /−12  =  

−60 /−12

m=5
